临床观察表明，再次经历症状是由刺激引发的，这些刺激在感觉上类似于创伤或其最糟糕的时刻之前不久出现的刺激。两个实验考察了知觉启动在这一现象中的可能作用。志愿者(N=28，N=62)观看了一系列“创伤性”和中性的图片故事，并完成了模糊物体识别(启动)和再认记忆任务。与中性故事中的物体相比，紧接在“创伤性”故事之前的中性物体被更强的启动，但识别能力并不更强。增强的引爆预示着随后会再次出现症状。研究结果支持知觉启动在再体验中的作用。
Clinical observations suggest that re-experiencing symptoms are triggered by stimuli that are perceptually similar to those present shortly before the trauma or its worst moments. Two experiments investigated the possible role of perceptual priming in this phenomenon. Volunteers (N = 28, N = 62) watched a series of "traumatic'' and neutral picture stories, and completed blurred object identification ( priming) and recognition memory tasks. Neutral objects that immediately preceded the "traumatic'' stories were more strongly primed, but not better recognised, than objects from neutral stories. Enhanced priming predicted subsequent re-experiencing symptoms. The results support the role of perceptual priming in re-experiencing.
